If you have a lung disease such as chronic obstructive pulmonary disease (COPD) or asthma, you are probably using an inhaler. There are several different types of inhalers, all of which deliver medicine into your lungs. Inhaled medications are the cornerstone of asthma and COPD therapy, but they can only be effective if they are used properly. Using your inhaler correctly delivers the medication to your lungs, where it can work to control your symptoms. Using an inhaler incorrectly means that little or no medicine reaches the lungs. Health care professionals and educators at the Lung Centre at Vancouver General Hospital and the Institute for Heart + Lung Health, with financial and technical support provided by BC Lung Association and Vancouver Coastal Health Authority Integrated Primary and Community Care have developed inhaler technique videos and booklets for Chinese (Mandarin and Cantonese), Farsi, Filipino, Korean, and English-speaking patients and uploaded onto YouTube.
